CaptureTheFlag

The 2011's CTF will again be held by FluxFingers, the CTF Team of Ruhr-Universität Bochum (Germany).
Last year's positive feedback has convinced FluxFingers to host another challenge-style CTF competition at hack.lu.
It is safe to assume that the usual topics are included: crypto, reversing, forensic and web security.
We are looking forward to seeing you participate - locally or from remote.
Direct your questions to somebody at our booth, a special email address will be released later on.

hack.lu CTF Registration is Open

This years Capture-The-Flag (CTF) contest of the hack.lu conference will
also be open for remote participants. However there will be only a
limited amount of teams accepted for remote participation so don't
hesitate to register as early as possible. To do so, please subscribe to
the mailing list of the CTF:
http://fluxfingers.net/mailman/listinfo/hacklu-ctf

Please, use your
team-name to register and a countrycode (i.e. DE for Germany), and only one subscription per team. Once
accepted, you will be provided with more information.

Note: The award ceremony will be held locally, so completely remote teams will not be able to receive a price and will receive a nice hack.lu t-shirt per mail instead ;). Still you will be having a lot of fun - we promise!

CTF-Access & Rules

CTF starts at 11:23. 87 Teams are registered. Local teams please come to our desk, near by the hackerspace.lu desk.
